Packing Patents (Class 81/8.1)
  • Patent number: 11376718
    Abstract: A packing screw removal tool for removing packing from a pump fluid end comprising: a tool body; a plurality of packing screw engagement dogs distributed about an axis of rotation about the packing screw removal tool; and a torque transfer engagement post coupled to the tool body. The engagement dogs align with and are releasably connected to radial locations on the packing screw. Applied torque is transferred through a torque transfer engagement post, through the tool body to the engagement dogs and into the packing nut. A second torque transfer engagement post is smaller than the first engagement post. The shape of the tool body allows rotation in limited or confined space. A pump may be serviced at the wellsite by utilizing the packing screw removal tool to unthread the packing screw from the fluid end.

  • Patent number: 9908224
    Abstract: Gland puller for use in rebuilding hydraulic cylinders. Upon insertion of the first end of the elongated rod into a shaft hole of the hydraulic cylinder gland assembly beyond a first point, the rotating protrusion member is configured to rotate from the first position to the second position, and upon rotating the threaded collar along the threaded portion towards the first end, the elongated rod is configured to be pulled back from the first point to a second point where a surface of the at least one end of the rotating protrusion member is configured to abut an inner surface of the hydraulic cylinder gland assembly while a surface of the threaded collar is configured to abut an outer surface of the hydraulic cylinder gland.

  • Patent number: 9902053
    Abstract: A knockout removal tool includes an electrical box. The front side is open. The electrical box may be positioned within a wall such that the front side lies on a plane that is planar with an exposed surface of the wall. A handle has a first end, a second end and an outer wall extending therebetween. The first end is flat. The second end is convexly arcuate. A rod is coupled to the first end. The rod has a distal end with respect to the first end. The rod is inserted through the electrical box such that the distal end is directed toward a knockout in the electrical box. A head is coupled to the rod. The head engages the knockout to facilitate removal of the knockout after the electrical box has been installed and trimmed.

  • Patent number: 7472716
    Abstract: A valve having a valve packing removal device attached thereto is disclosed. The valve may include a valve plug reciprocally disposed within the valve housing and connected to a sliding stem. The packing may be provided about the valve stem to ensure or minimize leakage of regulated fluid from the valve. A sleeve may have a diameter less than a bore in which the packing is disposed and may be connected to the valve stem such that when the valve stem is sufficiently pulled from the valve, the sleeve engages the packing and pulls the packing from the valve.

  • Patent number: 6918320
    Abstract: A packing tool or set of tools having a handle and one packing end that is formed to perform various tasks involved with packing fiber into conduits without damaging insulation on wires in the conduits. The tools are made of a non-conductive material that has a smooth surface on the packing end or ends with no sharp edges. In one embodiment the tools are made of injection molded plastic and are lightweight. One tool has a hook for picking up a single wire on one end, and a larger hook on the other end for picking up multiple wires. A further tool has a first end for packing and a second end with a mirror that is angled to facilitate inspection of the packing.

  • Patent number: 6625510
    Abstract: A computer-based system to create and modify documents used in a tool management program. A word processing module is used to create the document, in conjunction with a graphics module. The graphics module includes representations of all of the tools used in a maintenance program, as well as representations of toolbox panels into which the tools are placed. A user simply drags selected tools into selected panels to. create a tool-filled panel graphic which may be directly imported into the document in the word processing module. The tools also have certain attributes defined by associated data. A data interface arrangement is operable to convey certain selected data from the graphics module to the document in the word processing module, after preselected sorting.

  • Publication number: 20030029277
    Abstract: A tool for inserting and removing gaskets from hose couplings includes a shaft having a nose and heel attached at one end of the shaft. The heel includes a flat, bottom surface that is pressed against the gasket in order to push the gasket into place. The heel may have a sufficiently large surface area to not cause undue markings or damage to the gasket when it is inserted. When the gasket is to be removed, the nose is inserted between an underside of the gasket and the gasket seat. The heel is then moved into contact with the gasket seat and used as a fulcrum by which the nose is lifted away from the gasket seat. This lifting movement causes the gasket to be lifted out of the hose coupling.
